It is imperative that fire doors receive regular inspections. Frequency is likely to depend on many factors, including the age and condition of the door. It has been suggested that a minimum quarterly inspection rule may be applied.
Five areas to check when inspecting fire doors:
Certification : Look for a label or plug on top of the door to ensure the actual door is a fire door.
Gaps: Check gaps are acceptable for fire door compliance. Typically frame and threshold gaps acceptable are 3mm+/- 1mm at door to frame and 8-10mm at the threshold from floor covering to door unless a smoke seal is present. This can only be disregarded if specified on the test certificate.
Seals: Look for any intumescent seals around door or frame. Check they are intact with no sign of damage. Seals are required to expand in contact with heat in the event of a fire.
Hinges: Check all three hinges are firmly fixed with no missing screws. Be sure the door has been properly maintained and will perform in the event of a fire.
Closing Properly: Check door closes firmly onto the latch without sticking on the floor or frame. A fire door only serves its purpose when it can operate to a close position.
